The adjoining figure shows the variation of photo-current with anode potential for a photosensitive surface for three different radiations. Let 
and 
be the intensities and 
and 
be the frequencies for the curves a, b and c respectively. Then
A
and 
B
and 
C
and 
D
and 
Text Solution
Verified by ExpertsThe correct answer is:
B
We know that, stopping potential increases with increase in frequency. Therefore from figure, stopping potential 
but 
or 
.
Hence, 
but 
or 
.
Also, 
but 
.
Hence, correct option is , according to which 
and 
.
